Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188194, here are decompositions:

5 + 188189 = 188194
23 + 188171 = 188194
47 + 188147 = 188194
173 + 188021 = 188194
263 + 187931 = 188194
311 + 187883 = 188194
317 + 187877 = 188194
401 + 187793 = 188194

Showing the first eight; more decompositions exist.
